type t = [ `MaskedIterator | `Object ] Obj.tval of_pyobject : Py.Object.t -> tval to_pyobject : [> tag ] Obj.t -> Py.Object.tval create : Py.Object.t -> tFlat iterator object to iterate over masked arrays.
A `MaskedIterator` iterator is returned by ``x.flat`` for any masked array `x`. It allows iterating over the array as if it were a 1-D array, either in a for-loop or by calling its `next` method.
Iteration is done in C-contiguous style, with the last index varying the fastest. The iterator can also be indexed using basic slicing or advanced indexing.
See Also -------- MaskedArray.flat : Return a flat iterator over an array. MaskedArray.flatten : Returns a flattened copy of an array.
Notes ----- `MaskedIterator` is not exported by the `ma` module. Instead of instantiating a `MaskedIterator` directly, use `MaskedArray.flat`.
Examples -------- >>> x = np.ma.array(arange(6).reshape(2, 3)) >>> fl = x.flat >>> type(fl) <class 'numpy.ma.core.MaskedIterator'> >>> for item in fl: ... print(item) ... 0 1 2 3 4 5
Extracting more than a single element b indexing the `MaskedIterator` returns a masked array:
>>> fl2:4 masked_array(data = 2 3, mask = False, fill_value = 999999)

val next : [> tag ] Obj.t -> Py.Object.tReturn the next value, or raise StopIteration.
Examples -------- >>> x = np.ma.array(3, 2, mask=0, 1) >>> fl = x.flat >>> next(fl) 3 >>> next(fl) masked >>> next(fl) Traceback (most recent call last): ... StopIteration
